Ok, I have come back to this thread becasue I acquired a set of used GT40P heads off of an explorer, and I got my performer intake for My b day in March, and now I will be installing these this weekend. Pre 96 5.0 explorers until mid 1996 had normal GT40 iron heads. The 1996.5- 2001 explorers had the GT40P's. 87-93 e7Te mustang heads are a much better head than the stock heads on non gt40 351s. I have a complete 302 HO from an 87 5.0 mustang. But the gt40p heads are better than the e7te's in stock form. If you port a set of e7te's, you can get more power than with a set of stock gt40ps, or GT40's The gt40P flows more than the gt40 iron head stock. The P heads are nice for boats since for car use, the headers either need to be replaced, or hammered in to fit. The plugs are in the wrong spot for auto use. Good news for us marine guys.:) My P heads I got for 199 dollars, and had then 3 angle valve job, and head bolt holes enlarged to fit the 351w from the 302 it was on. They were also decked .60 to true them up, and had new brass plugs installed. With a full gasket kit for my pcm 351, it was 600 dollars total. My p heads came off of an explorer that should not have had P heads, but iron gt40 heads. It was made a few months before they were supposed to have had P heads, which is why I got them for 200 dollars. The guy wanted iron gt40 heads form the early Explorer for use in a mustang, so it worked for me. So, off I go to rip the old heads and intake off,and put the new upgrades on. I am certain I had a leaky intake manifold gasket/ seal. So hopefully this will cure my running issue that came up last year. And it wll give me a nice shot of HP as well:) I bought a Mr gasket 1932 adapter to mount the holley 4160 to the edelbrock performer intake, so hopefully it fits. I am guessing I will need a shorter flame arrestor, but that will be minor after I get all the rest of the top end done. |

We put a set of the Clearwater rebuilt heads on "Jbears" boat last year along with an intake and it picked up 5MPH, it went from 45 to around 50+ MPH and thats without a cam, not bad!

I talked to them too,they are rebuilt ones.He also said they had gone up and did not even know that there was a price on the web site.Anyway they are at 599 a set and 25ea for shipping.
When I talked to Clearwater they told me that the new castings are not done by Ford and they are now stronger in areas that needed it. |

Tim, Not only has their price gone up but when I bought mine about 1 1/2 years ago they were new castings, they seem to only show rebuilt now. |

Their price has gone up over the last year or so, but dont forget that they also install upgraded valvespings (good to .550 of lift), which is really a weak point on the stock P's if youre adding a cam. A good set will run you upwards of $130 plus install, so that brings the price right in line. I went the same route youre propsosing (bought used, had a VJ done) and if I were to do it again, I would go with Tristate. Just my 2 cents. If youre not planning on upgrading valvesprings, go with Clearwater- I dont see another way to get a complete set of rebuilt heads for $400. P's started being installed in Explorers in mid-97, I believe. Up to that point, 5.0 Explorers had GT40 heads, if my memory is correct. |

93-95 cobras had cast iron GT40 heads. 96.5- 02 IIRC explorers and the mercury version of the explorer that ahd 5.0 fords all had GT40 P heads, and those are a great choice for an inboard. I am looking for a set myself. and I will def go used, and have them rebuilt. 87-93 gt and lx 5.0s and 94-95 gt mustangs and GTS mustangs had E7TE heads. If anyone want a set of 120,000 mile 87 E7TE heads I have a set, but I really dont think there is much of a gain to drop those ona 351W PCM 240hp motor. there would be some gain, but not as much as the GT40 or GT40P heads. If you were to have the E7TE's "power ported" then they would be better than a stock set of iron GT40's. for what DIM sells their GT40's for I am shocked. and they are reg GT40's now, and not the P's. Tristate has sets of rebuilt gt40ps for 700 dollras,a nd I think that isstill too much. I bet I can find a used set of p heads for 100-150 and have a valve job done, totalling under 500 dollars. |

Do not feel bad I just learned how to post the links. I didn't know how for quite sometime. Boat doc I know how you feel deer season has been open since the 15th and I have only been out once. I am shooting for making it out a couple times this week. No pun intended. |

notice all of the flashing on the casting by the way. Oh and you only get flash on molded/pressure cast/formed materials, like die casting or plastic injection molding. Green sand molds equall no flash

spell check, where? why?
actually I installed a performer on mine, when I replaced the motor and I bought a chrome PP. liked the extra water passage, and what looks to be less porting work too. Was going to use it with the DO0E heads I had reworked. But there both sitting in a box now. |

Jim; Thanksgiving to Christmas is the only time I don't do Beam and Diet Coke. Something about the Holidays.
Spell check has been here for awhile. Haven't you noticed how it cleaned up 79's posts. Used to be only us guys who knew him could make out some of his posts...now everybody can understand him. Very bad that the '68 never got wet. I remember some of your posts with pics of the spring flooding...just kept it up all summer huh? john |

Hey jbear. Actually, from Thanksgiving to Christmas is the only time I drink hi balls (bourbon and soft drink over ice for all you kids out there). It's a religious thing with me.
When did auto spell checker show up on this thing???? Don't tell me it's been here all the time - I'm all ready losing my mind. I think because the '68 did not make it into the water one time this year. Not one time! It's been a crazy rainy year down here in Southeast Texas. |

Wow again. J-I-H and 79 are rolling into holiday form.
Actually guys...you all know how clueless I am. Thanks Brian for clearing up just what I have. And thanks again for getting it to me at the right price. As 79 said...when it went on it looked great and performs the same way. john |

Hmm... I'm speachless. But, as far as hammerings from 79 you ain't seen nothin' yet. That was pretty mild. Just wait until he's off his medication. So, do they have hot rods and racing in China? You never know about the world anymore. That Chinese company could be owned by Edlebrock and the minute they close their USA plant the Edlebrock name will start showing up on the Chinese castings. You never know... I wanna be a Grand Poobah too. And Edelbrock, if that's not your plant I'm totally sorry for the slanderous comment - don't sue me, it was only wild and crazy speculation from a guy setting near a bayou on a cold an rainy day with a glass of Turkey and 7-Up. I have no facts.

WOW. That was pretty accusational. I play with fords a LOT and I am part of the local mustang club and i help manage their forum board. I have done a lot of work on my car any other peoples cars in the club over the past 4 years. I have seen plenty of intakes and played and installed several. I have done a lot of porting work on intakes and am dabbeling a bit in heads now too. What I write on forum boards isnt just to say what I have heard or read on frivolus websites but what I have personally experienced. There is, in what I have seen with my own 2 eyes, more casting flash and a more porus sand used in the casting process of the PP intake than the edelbrock. I never said it was a problem, I just said there is more there than the eddy. The PP is not better in any area than price because it is based off of the performer design. It is cheaper because it is made in china and that is the difference in price.
So let me ask you this in rebuttal, have you ever held an edelbrock piece in your hands or are you quoting BS form a book or magazine. Thanks for hammering me and acting like a jerk like I have no clue. Im not some hopped up 18 year old who never seen an engine before, but you are quick to assume that. I never once it was junk or said anything negative to justify a comment like that form you. |

I would disagree with you completely. The intake we installed on Johns had no flash issues, and the Chrome version I have is flawless, both castings are equal to the Edelbrocks and the professional products design is much better in several area's. so are you talking from personal experince or quoting BS from a book/magazine because it sure doesn't sound like you have ever held a professional products intake in your hands. |

it is a knockoff edelbrock performer cast in china. The casting quality isnt nearly as good as a edelbrock. It is a great piece for the money and if you put a couple hours in with a dremel or air grinder to clean up the casting flash, it is even better value. |

John, that intake is actually a Power Plus Typhoon by Professional Products. The P/N is 54023 for anyone who is interested in purchasing one. They are the most reasonable priced Ford intakes (when buying new that is).
